Quick, March!

Four Aberystwyth players entered the Dyfed Rapidplay competition for March on Tuesday 9th. Rudy van Kemenade, as in the February competition, came first with a perfect score of 5/5. Tom Gunn scored 2½/5, I scored 2/4 (plus a full-point bye), and Sam Holman had a disappointing tournament with 0/4 and a full-point bye. Steynton's David Pinch and Scott Hammett were second and third respectively.
